To all whom itmay United States, residing UNITED STATES PATENT OFFICE-Q"! CHESTER McNEIL AND DUDLEY S. SEYMOUR, OF CHICAGO, ILLINOIS, ASSIGNORS TO UNION,

SPECIAL MAGHINEOOLLPANY, OF CHIOAGO, ILLINOIS, A CORPORATION OF ILLINOIS.-

Be it known 7 that .we, (Inn am MoNEr-L and DUDLEY: S2. SEmoun,--citizens. oh the at Chicago, inthe county ofi Cook, State of Illinois, have in.-

- vented certain-new anduseful Im rovemerits-in Bag- Cutting, an Conveying Apparatus; of whiclizthe following is a. escription, reference had tothe accompanying'drawing and to the-letters and figures of reference marked thereon,

The invention relates to an improvement in apparatus for use inconnection with the seaimng and delivering of bags.

As herein shown, the apparatus includes a supporting table orframework, a series of sewing machines for seaming bags mounted thereon, a conveying belt leading away from .each machine, and a single endless conveying belt extending beneath the ends of the other belts" to receive from said belts the sewed bags and deliver them to a suitable point.

, The invention also includescutting apparatus for severing the chain of stitching between successive bags, the severing taking place between the and delivering op eration. I

The invention consists in the matters hereinafter described and referred to in the accomlpanying claims.

e invention is illustrated in the accoln panying drawings, in which Figure 1 is a plan view of an apparatus embodyingthe invention; Fig. 2 is a front elevation; Fig. 3 is an end elevation; and Fig. 4 is a detail view, illustrating a form of cutting mechanism used in connection with tus for severing the chain of stitching between any two successive bags. This cutting apparatus comprises, as herein shown, a continuously runni from the main shaft of the sewing machine in any suitable manner, and cooperating with a stationary member. of the sewing machine has in rear of the needle and feeding mechanism, an elongated slot, so arranged that when a bag is fed ofl knife member operated The cloth plate BAG snnmro, cu'r'rme, AND convnirme APPARATUS.

from the machine, the chain. of stitching between itandfthe succeeding bag-will be drawn- 3 into the slot lfin the cloth late and intothepath of movementof the e-blades 2, 3, the knife blade operatingto-sever the chain This particular form ofcuttingitself formsno part of the present invention, but is simply shown by way of illustration, and as forming animportant' feature in the combination. It is, however, shown; described-and Seymour, Jan. 2, 1906, Serial No. 294,255.,

Upon the framework in rear of each marclaimed inan applicationfiled by Dudley S.

chine is a conveying belt D, trained overrollers a, on the shaft 0, and operated by connections with the line shaft. ing belts D are so arranged with res ect to These conveythe bed plate of each machine that w ien'the bags are seamed, they are carried by the belts D toward the rear of the apparatus and there delivered upon an endless conve er E, trained over rollers b on the framewor and extending along the entire length of said frame This endless conveyer E is also operated from the line shaft by suitable connections.

It will be understood that the speed of the first conveying belt must be properly roeportioned with relationto thespeed at w "oh the bags pass over the cloth plate of the sewing machine, so that there will be no amount of strain or pull upon the bags by the con:- veyer belt before they have assed from under the influence of the stitch-forming mechanism. This belt should referably travel at a s eed greater than the eed of the sewing mac line, which feeds the bag forward. If this conveying belt should run at a rate of speed slower than the rate of travel of the sewing machine feed, one bag would be piled u on another upon the conveying belt as sai conveying belt would not be able to take the bags away as fast as they are finished. If, on the other hand said belt is given a speed e ual or greater than the rate of speed of the eed of the sewing'machine, then as soon as the bag is fed on to the conveying belt, said belt would carry the bag along at the same s eed or a little faster than it is carried throug the sewing machine by the feed of said machine. Of course, said bag could not move faster than the feed of the machine until after the bag is completel stitched and the same passes from beneat the presser foot and feed. As soon howbelt and ca this movement of the bag b ever, as the bag is completed and the feed of the machine table, the rear s1de t ereof,

would drop by its own weight and on to the the chain of stitches into the cutter. If t e chain of stitches was not drawn taut between the bags, the falling of. the bag upon the belt by gravity would not carrythe chain of stitches into the cutter.

Having thus described our invention,

I what we claim as new and desire to secure by Letters Patent, is

1. In an apparatus for making bags, a suitable supporting framework, a sewing mechanism supported thereon and upon which the bags are sewed, a conveyer arranged substantially at right angles to the said sup orting framework and adapted to receive t, e bags from the cloth plate of the sewing mechanism, and a second conveyer arranged to receive the bags from the first conve er; substantially as described. 2. Iii a bag seaming and conveying mechanism, a suitable supporting framework, a sewing mechanism supported thereon, a conveyer for carrying the seamed bags away from the machine, said conveyer extending substantially at right angles to the supporting framework and to a position adjacent the rear edge thereof, whereby the seamed bags as the are fed from the sewing mechanism are de ivered to said conveyer and a second conveyer arranged to receive the bags from the first conveyer; substantially as described.

3. In a bag seaming and conveying mechanism, a suitable supporting framework, a sewing mechanism supported thereon, a conveyer for carrying the seamed bags away from the machine, said conveyer extending substantially at right angles to the supporting framework and to a position adjacent the rear edge thereof, whereby the seamed bags as they are fed from the sewingmechanism are delivered to said conveyer, anda second conveyer arranged to receive the bags. from the first conve er, and: a devicefor severing. the chain 0 stitching be-' I tween successive bags arranged between the sewing mechanism and the first conveyer b'elt w substantially as described.

4. In a bag seaming and conveying mechanism, a suitable supporting framework, a

series of sewing mechanism supported-ther'eon, a bag conve or for each machine, said conveyer exten ing substantially at right.

angles to the supporting farmework and .to a position adjacent the rear edge thereof, whereby the seamed bags as the are fed from the sewing mechanism are de ivered to said conveyer, and a single conveyer in such relation-to. all such conveyers as to receive the bags therefrom; substantially as described.

5. In a bag seaming and conveying mechanism, a suitable supporting framework, a

sewing mechanism supported thereon, a

conveyer for carrying the seamed bags away from the machine, said conveyer extending substantially at right angles to the supporting framework and to a position adjacent the rear edge thereof, whereby seamed bags as they are fed from the sewing mechanism are delivered to said conveyer, and an automatic cutter for severing the chain of stitching between the sewing mechanism and the first conveyer, and a second conveyer arranged to receive the sewed bags from the first conveyer; substantially as described.
